Symposium Information:

1. Symposium Dates:

Friday, January 11th and Saturday, January 12th

(Thursday, Jan. 10th for arrival; Sunday, Jan. 13th for departure)

2. Synopsis (objective):

The 7th North American Mössbauer Symposium will be held on January 11-12 (Friday-Saturday), 2013 on the campus of the University of Texas at Austin. This conference aims not only to bring together scientists from North America, but also to attract international participants. In the past, it was organized as Nassau or Nassau-Argonne Mössbauer Symposium.
Mössbauer Spectroscopy technique is an established method used by many different disciplines including, chemistry, physics, biology, geology, mineralogy, soil science, materials science and archeology and cultural heritage. The addition of synchrotron radiation based techniques has now extended the kind of information that can be extracted to include thermoelastic properties like sound velocity, vibrational specific heat, absolute value of atomic displacement, and phonon density of states. Furthermore, experiments under extreme conditions of temperature and pressure have now become common.
We are confident that with its unique depth and breadth, Mössbauer spectroscopy and nuclear resonant scattering of synchrotron radiation will continue to provide detailed understanding of physical, chemical, biological, and geological processes, earthly and extra-terrestrial alike. We plan to bring researchers from these diverse fields together for a two-day symposium in order to provide a chance to meet with each other in an informal setting.

We particularly encourage student participation by sending in their abstracts, which will be evaluated for oral and poster slots.

3. Symposium Venue:

The symposium will be held at the Jackson School of Geosciences, the University of Texas at Austin. The AT&T Conference Center on the campus of the University of Texas at Austin will be the primary symposium hotel. We have also reserved the Holland Family Center in the Jackson School of Geosciences as our “coffee break and social gathering” areas. The meeting room (JGB 2.216) and Holland Center are both located on the ground floor (2nd floor) of the JGB (Jackson School Building). If you drive a car, you can park your car in the San Jacinto or Manor Garage of the UT Austin Campus for a parking fee on Jan. 11th. Jan. 12th is a Saturday, and you can find nearby street parking for free (please obey parking rules on campus)–it is easier to access the building from San Jacinto St.

Austin, the capital city of Texas, is located only 15 miles from the Austin-Bergstrom International Airport, which has many direct flights to major US cities. Participants can also access Austin through nearby Dallas, Houston, and San Antonio airports. Austin is known for its live music on the Sixth Street (thus called the Live Music Capital of the World) and weather in January is expected to be a pleasure, with high temperatures expected in the low 60s or upper 50s. Check out Austin’s weather conditions here. Bring a jacket with you as temperature can drop significantly at night.

Most of the symposium activities will be within walking distance. The most convenient, cost-effective way to travel locally is to take a taxi or bus to/from AT&T Center from/to the airport (~25 dollars one way). Street parking space is very limited around campus, and you may expect to pay approximately 10-15 dollars a day for parking.

Here are some more information for your local activities:

(1). Local Attractions (click to download this Word file): We hope our symposium attendees can enjoy Austin attractions as much as the workshop activities. Highlights of these attractions include Zilker Park’s natural spring pool, State Capital, Sixth Street, and the UT Campus.
(2). Local Pubs and Eateries
(click to download this Word file): A short list of suggested pubs nearby when you feel thirsty and want to mingle with fellow attendees at nights. To enjoy live music along with a great downtown dining experience, try one the restaurants listed here.  Experience Austin’s Tex-Mex food, Texas open pit BBQ, and/or Sixth Street both within walking distance as well as several more famous locations that can be reached by a short drive.

4. Hotel and Guest Rooms (Deadline had passed):

Reservation cut-off date is December 11th, 2012. You may not get the conference rate if you make a late reservation!

Reservation for your guest room at the AT&T Center from Thursday, Jan. 10th through Sunday, 13th is now open. Please make your reservation as soon as possible. Two types of rooms are available: Standard King (~13 units available) andTower View Queens (~12 units available). The discounted room rate for the symposium attendees is $174 dollars per night for either one of the rooms. In the event that the King rooms were sold out, they may transfer you to the Queens. Two types of reservations are available:

(1). Online reservation:


(2) Telephone Reservation:

Tel: 877-744-8822 (toll free); 512-404-3600

Alternative hotels:

There are many nearby hotels that are less expensive (but perhaps not as convenient). You can easily find one online, or Goggle map (type “Austin downtown hotel”). If you chose to stay further away from the AT&T Center, please be advised that THERE ARE RUSH HOURS in Austin–try to have to sufficient time to fight through the traffic, especially on I-35 in the morning hours. Here are some potential choices:
(1). Double Tree Hotel: ~$120/night & up; walking distance of 20 minutes the department.

address: 303 West 15th Street, Austin, TX 78701
Tel: (512) 4787000 

(2). La Quinta Inn: ~$82/night & up; walking distance of ~30 minutes to the department. Good price, close to downtown Austin and the State Capital.

address: 300 East11th Street, Austin, TX 78701
