Tīmeklishibit the shape of a Lamb peak [31]. IV. RESULTS A few typical examples of spectra of the P(1) line of HD in the (2-0) band are shown in Fig. 3, where the absolute frequency is accurate to 1 kHz due to the lock of the diode laser to a frequency comb. The observed spectra of the P(1) line display the typical characteristic of a Lamb peak. For Tīmeklis2024. gada 11. apr. · Dip the lamb chops into the breadcrumb mixture to coat evenly. step 5. Transfer the lamb to a baking sheet. Cover the ribs with foil to keep them from burning and baking. Bake for 20 - 25 mins until the internal temperature reaches 130°F. step 6. Remove the lamb from the oven and let rest for 15 mins. Slice and serve. Enjoy!

TīmeklisThe width of individual Lamb dips, consisting of single hyperfine transitions, is about 1.5 MHz. This cor- responds with a spectral resolution of 7 x 10’ which is an order of magnitude larger than we could obtain by a stronger collimation of the molecular beam [ 41. The observed linewidth of 1.5 MHz is due to several effects.

Tīmeklis2003. gada 9. okt. · The Lamb dip in the power spectrum of a cw HF chemical laser has been observed.
