Mass Measurement on the rp-Process Waiting Point 72Kr
The mass of one of the three major waiting points in the astrophysical rp-process 72Kr was measured for the first time with the Penning trap mass spectrometer ISOLTRAP. The measurement yielded a relative mass uncertainty of delta m/m = 1.2x10-7 (delta m=8keV). Other Kr isotopes, also needed for astr...

| description | The mass of one of the three major waiting points in the astrophysical rp-process 72Kr was measured for the first time with the Penning trap mass spectrometer ISOLTRAP. The measurement yielded a relative mass uncertainty of delta m/m = 1.2x10-7 (delta m=8keV). Other Kr isotopes, also needed for astrophysical calculations, were measured with more than one order of magnitude improved accuracy. We use the ISOLTRAP masses of 72-74Kr to reanalyse the role of the 72Kr waiting point in the rp-process during X-ray bursts. |
