Mass Measurement of P to Constrain Type-I X-ray Burst Models and Validate the IMME for the A=27, T= Isospin Quartet

I. T. Yandow, A. Abdullah-Smoot, G. Bollen +12

Light curves are the primary observable of type-I x-ray bursts. Computational x-ray burst models must match simulations to observed light curves. Most of the error in simulated cur…

Identification of a potential ultra-low Q value electron capture decay branch in Se via a precise Penning trap measurement of the mass of As

M. Horana Gamage, R. Bhandari, G. Bollen +8

Background: Low energy and electron capture (EC) decays are important systems in neutrino mass determination experiments. An isotope with an ultra-low Q value -decay to an e…

Particle-in-Cell Techniques for the Study of Space Charge Effects in the Advanced Cryogenic Gas Stopper

R. Ringle, G. Bollen, K. Lund +4

Linear gas stoppers are widely used to convert high-energy, rare-isotope beams and reaction products into low-energy beams with small transverse emittance and energy spread. Stoppi…

First Penning trap mass measurement of Ca

J. Surbrook, G. Bollen, M. Brodeur +13

Isobaric quintets provide the best test of the isobaric multiplet mass equation (IMME) and can uniquely identify higher order corrections suggestive of isospin symmetry breaking ef…
