Abstract

Three spectral lines corresponding to Bohr orbit transitions

n = 3 \to 2

n = 4 \to 2

, and

n = 5 \to 2

in liquid

{}^{4}{He}

have been measured with a resolution of 340 eV. Intensities per stopped kaon were 0.09, 0.05, and 0.02, respectively. No evidence was seen for transitions to

n = 1

(intensity < 0.004).
