Abstract
The X-ray spectrum of muonic 237Np has been investigated with stopped muons in a NpO2 target, containing about 10 g of 237Np. The probability of the radiationless muonic 3d¿1s transition in 237Np, (9±4)%, was obtained by comparing the relative intensities of the main muonic X-ray transitions in singles and coincidence spectra. The coincidences were gated by the 2p¿1s transitions.
