We are using calorimeters with completely encapsulated sources to study low energy beta spectra. Our devices work as true calorimeters in the sense that they totally absorb and sum all the various quanta released in a decay into a single temperature

We describe electronics and signal processing techniques used to acquire data with our micro-calorimeters. The system includes front end electronics with cold FETs, an amplitude-independent trigger, pulse digitization and storage, and digital signal

Low energy beta spectra are studied with sources encapsulated in a superconducting Sn absorber. An NTD germanium thermistor measures the temperature transient (≈5 msec) caused by individual beta decays, and the total energy not given to the neutrin

We discuss various possibilities to improve the sensitivity of parity and time reversal asymmetry measurements in gamma decaying nuclei. We compare the best known parity violating case180mHf to a similar isotope178mHf. Although the parity violation m

Status of efforts to develop a cryogenic micro-calorimeter as a beta spectrometer for 17 keV neutrino searches is given. Experimental requirements are derived. Using NTD germanium thermometry, adequate detector performance (1.5 keV resolution at a ba

High-spin states in {sup 68}Ge and {sup 72}Se have been studied by in-beam, gamma-ray spectroscopy. In {sup 68}Ge the three known bands beginning at 8{sup +} are found to exhibit crossing transitions and other new positive-parity bands are discovered

An investigation of low-lying energy levels of $^{130,132}\mathrm{Ce}$, $^{132,134}\mathrm{Nd}$, and $^{134}\mathrm{Pm}$ has been made via \ensuremath{\beta} decay, especially of those levels in the ${\mathit{K}}^{\mathrm{\ensuremath{\pi}}}$=${2}^{+}
