Bennett, N. Zhelev, A. Fefferman, K. Fang, J. Pollanen, P. Sharma, W. Halperin, J. Parpia] We present results of the Q −1 and period shift, ΔP, for 3He confined in a 98% nominal open aerogel on a torsion pendulum. The aerogel is compressed uniaxially by 10% along a direction aligned to the torsion pendulum axis and was grown within a 400μm tall pancake (after compression) similar to an Andronikashvili geometry. The result is a high Q pendulum able to resolve Q −1 and mass coupling of the impurity-limited 3He over the whole temperature range. After measuring the empty cell background, we filled the cell above the critical point and observe a temperature dependent period shift, ΔP, between 100mK and 3mK that is 2.9% of the period shift (after filling) at 100mK. The Q −1 due to the 3He decreases by an order of magnitude between 100mK and 3mK at a pressure of 0.14±0.03bar. We compare the observable quantities to the corresponding calculated Q −1 and period shift for bulk 3He.
